Notes: The READ function
reads a total of num values starting at file
position and places those values into memory locations starting
at memory location. Parameters may be constants or variables.
The values read may consist of bytes, integers or floating point
depending on the format specified by the preceeding OPEN
statement.
file position is expressed in elements, not bytes. For
example: If the data type is floating point then the 10th element
is 40 bytes from beginning of the file. If file position is
larger than the actual file size an error will occur.

Examples:

# Read and display 20
values from a file# Create a 16K file
